BW already beat all of DC and Superman (110% canon to everything) so he wins. Stomps actually. Statues his ass and goes to town.
Seriously though, I don't really feel like there is enough hard feats for him for actual matches.
Black Thor consumes Universes and created Galactus meaning that Galactus has a small fraction of his power. Ok cool. That's ****ing awesome actually but we don't know how much.
Also, how many characters do we have in comics that consume universes and multiverses and all this nonsense but then get shitstomped by freakin Squirrel Girl or Jubilee or some shit?
I'm just saying eating Universes these days is pretty vague and I'm honestly feeling like they are just eating Universes because it's the thing to do🤣
